Hello, I have been playing the Ayanami raising game for a while now,i have triggered most of the event for Rei, but for some reason i cant make appear the one where Rei is standing alone in the street and starts to rain. What do you need to do to make it appear? I have been looking in guides but none of them has it.

It happend when Rei get lost in the city when she go out alone or something?

This is the image of the event (In an album of all the other events, you will know what im talking about.)
